How Space-Based Internet Works (e.g., Starlink) Space-based internet uses satellites in low Earth orbit (LEO) to deliver internet to users anywhere on Earth. Here’s the step-by-step process: Satellites in Orbit – Companies like Starlink launch thousands of small LEO satellites that orbit the Earth at altitudes of 550–1,200 km. Unlike geostationary satellites, LEO satellites move quickly relative to the Earth’s surface, reducing latency. Ground Terminals (User Dishes) – Users have a satellite dish or terminal that connects directly to the satellites overhead. This dish automatically tracks satellites as they move across the sky. Data Transmission – Data from the user’s device is sent to the terminal, uplinked to the satellite, and then transmitted either to another satellite in the constellation or to a gateway on Earth connected to the internet backbone. Internet Access Anywhere – The gateway routes the data to the internet, allowing seamless access even in remote or u...

Smart Dust: The Future of Tiny Technology Smart Dust refers to microscopic wireless sensors —often called “motes”—capable of sensing, computing, and communicating data about their environment. These tiny devices, sometimes smaller than a grain of sand, combine microelectromechanical systems (MEMS) , wireless communication, and energy-harvesting technology.
